Hoppers 18 and 18' for collecting spilled seeds are attached to the left and right sides of the seed box 5, respectively.
19, 19' are the upper edges of the recovery hoppers 18, 18'. The seedling raising box 2 has a collection hopper 18,1
8' are respectively placed symmetrically at the outer positions.

FIG. 1 shows a state in which the seedling growing boxes 2, 2 are placed, and FIG. 2 shows a state in which the seedling growing boxes 2, 2 are removed. A specially shaped seed suction box 20 is provided above one of the seedling growing boxes 2 placed on the left and right sides.

The size of the seed suction box 20 is about the same as the seedling raising box 2. The seed suction box 20 is a square box, and in particular, its bottom surface 21 is completely horizontal.
Furthermore, the bottom surface 21 is not allowed to be charged with static electricity.
Made of high quality stainless steel plate.

The seed suction box 20 moves horizontally from a position directly above one of the seedling growing boxes 2, slides on the upper part of the wiper-like scraping piece 11, moves further laterally, and reaches right above the other seedling growing box 2. and stop. The seed suction box 20 is attached to the frame 1 so as to be able to move laterally, but in this case, the bottom surface 21 is always in contact with the scraping piece 11 and moved horizontally.

will be established.

A contact plate 31 which is larger in area than the seed suction box 20 is brought into contact with the upper surface of the seed suction box 20 , and the contact plate 31 and the seed suction box 20 are fixed with screws 32 .

Both left and right ends of the plate 31 project laterally beyond the seed suction box 20, and leveling tools 33, 33' are attached to the projecting portions 32'32'', respectively. Leveling tools 33, 33' The coil wire 35 is also of a special structure, and a coil wire 35 is loosely fitted around the outer periphery of a metal round rod 34. Both the metal round rod 34 and the coil wire 35 are in contact with the surface of the seeds in the seed box 5. At that time, the seeds are also moved back and forth to some extent by rotation due to the contact resistance of the coiled wire 35.

Both ends of the metal round bar 34 are bent at right angles to form a bent portion 36, and the upper end of the bent portion 36 is inserted from below the protruding portion 32'32'' and fixed with a screw.

Suction holes 37 are formed in the bottom surface 21 of the seed suction box 20 at positions corresponding to the centers of each of the squares 4 of the seedling raising box 2 for adsorbing two to three ultrafine particles such as Chinese cabbage seeds. The suction hole 37 is formed so that a seed fits therein.

There are two suction ports 3 on the top surface of the seed suction box 20.
8, 38' and a plurality of inlets 39... are opened. The two suction ports 38 and 38' are the numerous suction holes 3 bored in the bottom surface 21 of the seed suction box 20.
7, the location is specially designed to ensure that the seeds are sucked in with the same suction force.

In other words, the dimensions of the seedling box are 1:2 horizontally, so when viewed from the front and rear, it is at the center of the left and right sides, but when viewed from the left and right, it is at the center of each of the front and rear half halves. Each is open.

The two suction ports 38, 38' are connected by one suction tube 40 as shown in FIG. 4, and a bellows 42 connected to a suction blower 41 is connected to the center of the suction tube 40. A large number of inflow ports 39 formed in the seed suction box 20
... are lined up in a straight line in the front-rear direction, and valves 44 that are moved up and down by two solenoids 43 and 43' at the front and rear are respectively attached to their upper surfaces.

The solenoids 43, 43' are respectively fixed to protrusions 45, 45' which protrude upward by the contact plate 31, and each actuator 4 of the solenoids 43, 43'
Each valve 44 is attached to the connecting rod 47 at 6, 46', and when the solenoids 43, 43' are energized,
A plurality of inlets 39 are formed to open simultaneously.

This is because if the inflow ports 39 are simultaneously opened by the solenoids 43 and 43', an impact will be applied to the seed suction box 20.

The seeds described above contain a large amount of oil in their epidermis itself, so if they are strongly sucked and adsorbed, they will stick to the suction port 37 not only by the suction force but also by the adhesive force of the oil. Because of this, it does not easily fall under its own weight.

8 and 9, the detailed structure is exactly the same as the prior art described in detail above, but the suction blower 41 and the motor for rotating the suction blower 41 are integrated on the upper surface of the seed suction box 20. The only difference is that the bellows 42 is fixed, and therefore the bellows 42 is not required, simplifying the structure.

(effect) Next, we will discuss the effect.

The operation of the present invention will be explained, but as described above,
The present invention differs from the prior art only in that the suction blower 41 and the motor for rotating the suction blower 41 are integrally fixed to the upper surface of the seed suction box 20, and the action of sowing itself is as shown in FIGS. This is the same effect as the structure shown in the figure.

Therefore, the seeding action shown in FIGS. 1 to 5 will be described as follows.

Fill the seed box 5 with seeds such as Chinese cabbage, cabbage, or cauliflower, and turn the manual handle 1.
7 slightly to move the bottom member 7 upward a little,
Some of the seeds are wiper-shaped scrapes 11, 11
Hopper 18, 18' for collection a little beyond
Make sure it spills over.

In this state, place the seedling raising box 2 on the horizontal table 3 on the side where the seed suction box 20 is not located, and turn on the switch.
, the suction blower 41 rotates to open each suction hole 3.
Inhale air from 7.

When the motor 25 is energized, the pinion gear 28 fixed to the rotating shaft 27 rotates to move the seed suction box 20 to the right, for example in FIG. 2. When the seed suction box 20 moves to the right, the top surface of the seeds in the seed box 5 is leveled by the leveling tool 33' attached to the right end, and the bottom surface 2 of the seed suction box 20 is leveled.
1 slides on the upper surface of the seeds, the seeds are absorbed by the suction holes 37 formed in the bottom surface 21, and the seeds are completely fitted into each suction hole 37.

When the seed suction box 20 moves further to the right, the switch 3
0', the seed suction box 20 stops at the upper part of the seedling raising box 2, and the solenoids 43 and 43' are energized to move the inlet port 39 upward, thereby removing the seeds adsorbed in the suction hole 37 and raising the seedlings. It is dropped into the square 4 of the box 2.

When the manual handle 17 is moved upward in accordance with the decrease in the number of seeds in the seed box 5, the seeds in the seed box 5 can be sucked one after another and sown until each seed is used up.

(Effects) The present invention has the above-mentioned configuration, and in particular, the gist is that the suction blower 41 and its motor (attached to the suction blower 41) are directly fixed to the upper surface of the seed suction box 20, and therefore, Compared to the bellows-equipped seeding device of the prior art, the structure is simpler in that it does not require bellows, and since the suction path is shorter, the suction force is stronger and there is no malfunction.
